TO ALL WHOM IT MAY CONCERN:

Be it known that I, J. A. HALL, of. Greenfield, in the county of Hancock, and the State of Indiana, have invented a new and useful improved Grain-Cleaner; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, making part of this specification; and in which- Similar letters indicate corresponding parts.

Figure 1 is a vertical longitudinal section.

Figure 2 is avcrtical transverse section.

Figure 3 isan elevation of the discharge end of the revolving screen.

The screen revolves one. horizontal axis. circular series of cams on the head of the screen gives a snltatory motion to the hopper and sieves above through which the grain first. passes. A registering shutter on the discharge end of the screen opens and closes the edu'c'tion openings.

In the drawings, A is a hopper, and B B are two sieves on the shaking-box C, which is hinged in the standards I) D, and has an up-nnd-down motion given to it. by the contact of the cams E E with the projection F on the under side of the shaking-box. The screen G has two heads and a. wire-cloth covering, and rotates on a horizontal axis, H, by'power applied to the crank I. It receives grain from the spout J nt't er it-has passed through the two sieves B B, where the larger offalis removed and falls from the openings 6 b The grain from the spout J falls on to the plate K which discharges it into the revolving screen through the opening in the head of the screen. As the rotation of the screen continuallybrings the grain against a new portion of the wire screen, the finer offal falls through the meshes and is received in-and discharged from the hopper L. The clean grain is discharged at the openings M M, at the opposite end of the screen from that at which it was received, and falls into the spout N which conducts 'it out of the machine. If it be desired to keep the grain in the screen for awhile to remove every trace of offal, theshntt-er P is rotated so as to shut the openings M. The head 1 of the screen and the shutter P have openings through them of the same size, which permit the grain to passwhcn they register, as in fig. 1, but when the shutter is rotated, as in red lines, fig. 3, the passage of the grain is blocked, and it may be retained in the screen as long as desired. The spring R, lJy-cngegcment with holes in the head y, retains the shutter in the position desired.

Having thus described my invention, what I claim therein as new, and desire to secure by Letters Patent, is-

1. The shaking-shoe C, hinged to the frame, and agitated by contact with the circular series of cams or projections on the' head 'of the rotating screen, substantially as described.

2. The rotating screen G, in combination with the shaking-shoe C, and the shutter I for regulating the discharge, substantially as described. b

To the above specification of my invention I have signed my hand this 20th day of March, 1867.

J. A. HALL.
